Mini Cupcakes Sold Calculation

A local bakery sells two sizes of cupcakes: regular and mini. The ratio of regular cupcakes to mini cupcakes sold last week was 5 to 3. If the bakery sold a total of 80 cupcakes last week, how many mini cupcakes were sold?

Let the number of regular cupcakes be represented by $r$ and the number of mini cupcakes by $m$. Based on the ratio, we can express this relationship as:

$$ \f\frac{r}{m} = \f\frac{5}{3} $$

Additionally, we know that:

$$ r + m = 80 $$
